“I am the astronaut of boxing. Joe Louis and Dempsey were just jet pilots. I'm in a world of my own.”

Simplified Meaning:

This quote is about someone expressing how they believe they have taken their skills to a level far beyond those who came before them. The speaker is saying that, like an astronaut who travels into space goes much further than a jet pilot who flies within the Earth's atmosphere, they also reached new heights in their field compared to others. In real life, think about how technology has evolved. Early computers were amazing when they were first made, but today's computers are so advanced and powerful, it's like they're from a different world. Similarly, the speaker is proud of their achievements and feels they have accomplished something extraordinary that sets them apart. People can apply this idea by always striving to push boundaries and improve themselves, aiming to achieve more than what was previously thought possible.
